About 100 Redland residents turned up to grieve and pay tribute to the six months' pregnant woman and her partner who died out walking their dog when hit by a stolen car on Australia Day.

In an emotion-charged event, Ms Leadbetter's Aunty Danielle spoke on behalf of heartbroken family and friends, saying there had been a great outpouring of grief and support.

"People are here who did not know them," she said. "We've just met the people in the other car (rammed before the fatal accident).

"I just want to thank all these people for their kindness and support."

Tears fell as neighbours, relatives, friends and residents laid a mass of wreaths, candles and toys at the intersection on busy Finucane Road.

"The family now needs to grieve," Ms Leadbetter said. "And after that, we want change in the law."

She said laws should be rewritten to ensure that people convicted of crimes were made to serve their time.

"We don't want this to happen to other people. Someone could get killed over a set of car keys."

Ms Leadbetter said she had spoken to local political representatives, police and a pastor.

Cr Tracey Huges said it was such a tragic event that it had impacted an entire community.

A Waterford West teenager has been charged with two counts of murder and the matter was mentioned in Children's Court today, although he did not appear.

Police allege the 17-year-old was driving a LandCruiser which had been stolen from a Cleveland property between 4pm and 5pm.

The teenager also has been charged with dangerous operation of a vehicle, two counts of burglary and one count each for unlawful use of a motor vehicle and attempted unlawful use of a motor vehicle.

Police say the four-wheel-drive went through a red light and hit a truck before it struck the couple. They died at the scene.

The teen was filmed when the vehicle he was driving and a silver Hyundai collided earlier at the intersection about 15 minutes before the fatal crash.

Assistant Commissioner Brian Codd said it was understood that Ms Leadbetter was pregnant.

"My thoughts and the thoughts of our team are very much with the family and friends of the victims," Assistant Comissioner Codd said.

"Here are two people going about their business innocently on Australia Day ... they should be entitled to do that. Now to have them ripped away from their families is an absolute tragedy."

Police were notified that the vehicle had been involved in an incident at the same intersection earlier in the afternoon but could not track down the driver before the fatal crash.

The teenager was tested for drugs and alcohol.

Assistant Commissioner Codd said he could not go into the teenager's history but reports of the juvenile being on bail for a number of offences were inaccurate.

He appealed for people with information or CCTV footage to come forward.

The couple's dog Frankie went missing after the crash but was found this morning.
